I agree it's an absolutely superb model and say that without hesitation. I would have preferred it to have the same haulage capacity as their equally nice D Class and, personally, have no aversion to traction tyres if they run true, as my D Class and Hornby T9 do.
It's got me wondering whether the geared driving axle from the D Class would fit as a direct replacement - surely it should - so if anyone with traction tyre phobia has swopped their traction-tyred D Class leading axle for the plain one that was supplied and would like to part with it......!
As has been said, 4-4-0s are a problem in 00 but I have a few old Wills and K's [with Portescap or XT60 motors] that I built in the 70s with the tender lightly bearing on the rear of the loco. They will haul almost anything but of course the detail doesn't compare with today's offerings.
